Your reply is a good example. I haven't seen anyone in this HN post's comments talk about how myopia works. I legitimately do not understand why so few people know even the basics of myopia progression. All of these comments are, pun intended, the blind leading the blind. I especially don't understand it given how common myopia is and how important it is for parents to understand it for their children.

1. Glasses that blur what's on peripheral vision https://abc11.com/amp/4176773/

> too much time spent in front of a screen confuses the eye, since everything is in focus. The eye keeps growing, leading to myopia.

2. Glasses to stop myopia are successful in multi-site trial https://newsroom.uw.edu/news/glasses-stop-myopia-are-success...

Glasses with fogged edges prevent over focus:

> What’s supposed to happen as your eye grows, is that things should begin to go out of focus in the periphery of your vision. That’s a signal for the eyes to stop growing.

3. Multifocal contact lenses slow myopia progression in children https://www.nih.gov/news-events/nih-research-matters/multifo...

4. Putting contact lenses on monkeys _causes_ myopia and removing them slows myopia growth https://www.nature.com/articles/s41598-019-48009-3

5. "How Atropine Eye Drops Can Slow Myopia Progression" https://www.myopiainstitute.com/eye-care/how-atropine-eye-dr...

> Applying atropine eye drops dilates the pupils and temporarily paralyzes the focusing muscle inside the eye. It also relaxes the eyes’ focusing mechanisms.

Your eye grows without your brain's involvement. Sharp focus on the back of the eye, especially in the periphery, tells the eye to grow longer because it's overfocusing. This leads to the worsening of myopia. Things that cause sharp focus on the retina and fovea: contacts, glasses, and holding things close to your face that keep everything in focus. This may be why being outside is correlated with slowing myopia progression, because you wont have things constantly in focus in your peripheral vision from it being close to you.

I have a serious question: did you not come across any of this research? No one seems to have familiarity with these concepts in this HN thread. Did you see articles like these and skip over them? Or, maybe, were you only googling for myopia and sunlight, which is unlikely to return results like these?
I don't really understand the downvotes and reactions of the other commenters to the gp's post. There's a whole bunch of studies showing there's less incentive to find cures opposed to ongoing treatments under for profit health systems.

On a website where products as a service are discussed regularly i'm confused as to how the parallels between that and profit driven 'healthcare as a service' are ignored or looked at with hostility.
Sure. What if they can't borrow them though? What if they are owned by retail/institutions/board? Some conservative estimates put WSB holding 7-8% with some people owning .2-0.4% and that is without the lurkers.

Same thing happened to Volkswagen, only 1% of the shares was available for purchase and they had to close their positions.

Postgres has materialized views for the case of expensive queries. Instead of doing a view query in real-time it physically caches the results and has the same accessibility as a regular view.

They don't solve all situations with expensive queries but they help a lot. The fact they behave like dynamic views means you can migrate a dynamic view to materialized if you run into performance issues without making changes to the client application. With views in general you can shuffle around tables and relationships without the client application knowing or caring.
To play the devil's advocate, suppose we show that organic life can spontaneously emerge from basic building blocks under certain conditions. Even then, there's a chance that those conditions were not present on Earth when life appeared here. It might be the case that a God had to artificially create them. And the first life was here billions of years ago, chances are we can't ever be sure.

By time seen I don't literally mean time displayed on screen but more like TV/radio ads, as in this ad will be part of our rotation of X ads for an entire months across X publishers. I think The Deck used to do this.

Determining the price will be a bit tricky (and I would expect that you'd have to lowball yourself until your platform builds credibility in terms of good ROI) but in the long run it should mean your advertisers pay a flat price to be included per week/month regardless of actual impressions or clicks (thus there's no fraud potential as only the raw profit from the ads will matter - the only "fraud" potential would be to literally buy the advertised product en masse).

I Love Reading 1980s Computer Magazines, and So Should You
Perhaps the most interesting part of this review is how there seemed to be a plan to work with OEMs in creating Ryzen 4000 laptops, and transitioning them to Ryzen 5000.

> AMD made both sets of processors pin-compatible, allowing OEM partners to build designs that could be used for either processor family.

Last year was interesting for laptop buyers, though it took a while for the various Ryzen laptops to be announced and available, and the year was wrapped up with Apple Silicon M1 laptops.

This should be an even more interesting year as higher-end Ryzen laptops supplant the previous versions. The performance is better and availability might be better, too.

I was disappointed not to see a more direct comparison of power consumption and battery life between Ryzen 5000 and Ryzen 4000 (with the caveat that the specific unit reviewed has no exact predecessor.)

AMD claims

> a +2hr battery life from a simple processor swap from Ryzen 4000 to Ryzen 5000, even if everything else in the chassis is the same
A USB flash drive. I could not believe how much storage it had.
I agree this behaviour is weird. When I look at iOS users on Safari, or Chrome, I feel like I'm using Windows 3.1.

Here's what I do on FF:

- When visiting a site, on the hamburger menu, there is a "add to main sites" icon, which adds the site to the home screen of Firefox.

- In the global prefs, I changed back to always displaying the location bar at the top, and always present (the scrolling was annoying me).

- We can long-press the tab icon, to open a new tab.

So if I'm on a site, and want to open HN:

- Long press "New Tab"

- Tap "HN" icon on the screen.

It's still annoying that it opens the keyboard by default. It sometimes adds a few milliseconds of lag, but I guess then search-heavy users would complain about the extra tap.
Ask HN: How to measure Product/Market Fit from marketing
My brother and I are working on marketing a new D2C app we built. My question is: based on marketing, how can we measure how good our product/market fit is? For example, if we spent $1000 on marketing, what kind of response should we expect if we have a good product/market fit? Another way to word this is: what should the customer acquisition cost be for a brand new D2C app (right off the starting line)?
Very interesting! Hopefully they have more success in the future. Seems like an enormous market so hopefully there will be more investment.
Yes, so we arrive at “if I understand this correctly, it is not a problem, or a lesser or different problem” as I first asked.

I find this distinction to be bereft of a proper justification. As I said elsewhere, I cannot think of any salient reason to not cover name and address as a means to identify a person, but do cover far more obscure and unlikely biometric data.

It should not be protected in any different way.

docker and k8s adoption can force a company that over years has developed and perfected a standard practice of deploying application, with a half-ass'd solution that ends up solving the wrong problems and costing way more. The "shipping beats perfecting" mantra is very much at play here. This is due to the amount of time it would take to achieve parity. At the end of the day, the new solution ends up looking like a step-back.

Such a practice combined with the mentality that software engineers should do their own dev-ops can easily lead to an environment of spaghetti applications where every developer working on the new platform does things slightly different because the replacement solution wasn't complete and had to be addressed by countless band-aids by engineers across the band of talent.

Furthermore, for the features that were able to achieve parity, you're now forcing your entire organization to re-learn the new development process. The docs our abysmal and the software engineers that developed the original solution have moved on since the hard work of "productionalization" remains and they're not interested in that.
>but web advertising and trackers are already responsible for a huge chunk of performance issues already.

Indeed. The brave move would be to firefox to include built-in adblock, but I don't think Mozilla has the cojones.

>Of course we'll have the inevitable guy pop in here and talk up how awesome web tracking is because it helps sites monetize better, but that's all bullshit.

I think if adblocker usage became widespread we would in fact see the death of a lot of websites, but to be perfectly honest I kinda want that to happen because advertising is cancer.

Pay my taxes through some one-off browser made by an organization that wouldn't/couldn't otherwise update their software in time to make the cut-off? Yeah, that sounds secure and like something I want on my machine. Oh, wait, I have a Mac...

(The joke in that last sentence is that the browser, to add insult to injury, only runs on Windows.)
I use the noscript extension that uses a scripting whitelist. Bit of a pain at first, but pretty soon your browser will be flying. No extra hardware needed.

Kid's computer has dnsmasq as a similar solution.
I'm not sure what world you're living in, but the failure rate so far has been much higher than what Musk has said. Is it bad? They said 1%, it's 5-6%. Should we count the early satellites? Why not? The newer ones haven't been up long enough to tell how reliable they'll be. He also said they want latency < 20ms on Starlink. Again, not going to happen because of physics, but that didn't stop people from repeating it over and over despite the service being 40ms+ on average. Sure, you CAN hit 20ms if you are next to a POP and your endpoint is a single satellite hop, but that's not the norm.

To be frank, it sounds like you don't understand the industry very well, and that's ok. But not everyone forgets what was said in 2015 when the project was launching. Since you asked, here's one non-truth:

https://licensing.fcc.gov/myibfs/download.do?attachment_key=...

>High capacity: Each satellite in the SpaceX System provides aggregate downlink
capacity to users ranging from 17 to 23 Gbps, depending on the gain of the user terminal
involved. Assuming an average of 20 Gbps, the 1600 satellites in the Initial Deployment
would have a total aggregate capacity of 32 Tbps. SpaceX will periodically improve the
satellites over the course of the multi-year deployment of the system, which may further
increase capacity.

This ignores A) competitors who have first priority on the spectrum, B) 80% of the satellites are over water and completely unusable during that time, and C) more recently we know that the user terminal at best would perform lower than the 17Gbps low end they cite due to cost-cutting on the scan and G/T of the antenna.

If you believe it's okay to lie in FCC filings so that you win awards and change policies, then that's a valid opinion to hold.
I'm not OP, but I have my browser setup to block trackers only, nothing that's billed as an ad-blocker.

I use Firefox with Strict Enhanced Tracking Protection [0] and Privacy Badger [1] as an extra layer of protection. Some sites, mostly news orgs, complain that I'm blocking ads, but inevitably these are the sites Privacy Badger reports 20+ trackers blocked. I'm happy to see ads online, I'm just not willing to sacrifice my privacy for them.

I don't know how it compares to Chrome but it's definitely fast enough to leave me with no complaints. I'm using it on Samsung A40 and Tab 5e, plus a Sony Xperia X Compact. Also as my primary browser on my laptop (Ubuntu 20.04).

> Now their latest political stunt has got heads rolling

Care to elaborate?

I assume the "political stunt" part was related to all the Trump deplatforming stuff a few weeks back.

Hadn't heard anything related to anyone actually getting any pushback for it though.
The way they phrased it, in the post implies otherwise?

> These impacts are similar to those reported by the Chrome team for similar cache protections they are planning to roll out.
No worries, thanks for the suggestions. I didn't read them as complaints at all.

I updated the link too, I switch back and forth between vim/neovim, the only real difference to me is the location of the config file.
Migrate Environment Variables (ENV) to Rails Credentials
Hi all,

Rails credentials have been around for a few years. Yet, many guides, articles, and how to still mention the use of ENV's. To help you understand why it's beneficial and how you can do it in a short time for any of your projects, I've detailed a step-by-step plan. Hope it helps some!
Thank you! Exactly :)
Favicons are mentioned in the article as one of the caches that get partitioned now.
I understand that, but I don't see what is so complicated about reporting # of HIV tests conducted in a certain timeframe (daily, monthly, whatever) and what portion of those tests came back positive, just like we currently do with coronavirus. It doesn't matter what the lag time is in between being exposed and receiving a positive test. What we are interested in is # of positive tests, why is there a 3 year lag here?

I can't help but to feel just like the author of this article.

I'm vastly in favor of taxing and hurdles as natural filters. Mainstream spoils everything (~almost). You end up having people not really into things, endless debates about side features, about how to organize the projects (inclusiveness, code of conducts, tooling), scandals and less about the passion of doing the thing.

I'm often amazed at the difference in pacing and communication on Mailing Lists. It's slower but denser.
It only seems to apply to the DOJ, not other agencies like ICE, and it only means they can’t renew the contracts.

Even in the 10 years or so that I’m sure such contracts exist, nothing seems to mention what we do with the prisoners afterwards.

> My bank still accepts fax documents. All I would have to do is find a fax machine ...

On linux you can use [efax](https://linux.die.net/man/1/efax) and a modem and... ooops, good luck finding a modem.

I did this for real ~10 years ago when a stupid company didn't accept a scanned PDF by email and required a fax of the actual document "because security". The difference is that I had a modem in an old laptop at that time, so I just send them the same scanned PDF.

Now I'm wondering if there is a provision for sending faxes somewhere in the GSM/3G/4G rabbit hole of standards.

> Windows 2000 was super neat compared to the old clunky Win 98

My dad had a friend with an MSDN subscription, so we got a pre-release developer copy of Windows 95. Moving from Windows 3.11 to that was pretty jaw dropping.

But after a while we had an issue with the machine. Sectors on the hard drive were going bad, so we brought it into a shop to have someone confirm that. When we booted it up in the shop the tech's eyes went wide and I think he started drooling a little bit. He offered to swap the drives and copy all of our data from one to the other for free (I assume he thought he could make a copy of the OS for himself too). We declined and he was pretty crushed.

I've done that. I've also reinstalled windows 10 and reset my pixel 3a android phone. It doesn't seem to be helping. The malware still seems to be there. I think I need a malware removal or malware analyst service that can remove really bad malware. Places like geek squad and micro center would probably not be of any help, I've tried scanning with a lot of popular anti-virus software and it doesn't detect anything, I might have something called FUD (fully undetectable) malware but I'm not sure if this is the right terminology.

Bitdefender and malwarebytes have also thrown notifications about suspicious connection being blocked when I went to popular websites (like google or flipboard.com) that should be safe. It feels like the attacker is triggering the notifications as a way to intimidate me, as if the attacker has access to my computer and phone and is violating my privacy and this is a way of reminding me of that.

Also Google looked really different a while ago like a 90s version of Google, and text on Google showed up in other languages, and asian (chinese, japanese, or similar) profiles show up on dating sites and apps often, these are not profiles of normal asian people. Thank you.
